iland,have invented certain Improvements in Presses, of which thefollowing description,

in connection with the accompanying raw-v ings, is a specification, likereference characters on the drawings indicating like parts in theseveral figures. l I

This invention relates to pressesof the member is movable relatively toa bed to e set a ressure ap )lying operation in connection t mmwith.resses of this type are used for many different purposes and frequentlythey are used-in connection with movable dies for dying out sheetmaterial such as leather.

The invention isv shown as embodied in a machine especially adapted foremployment for the purposes just specified, the illustrated machinebeing adapted especially for dying out thin sheet material such as skinsof upper leather, and to machines intended for such uses the inventionis particularly applicable, as will appear hereinafter.

Presses for dying out upper leather are preferably constructed so that aconsiderable surface of the leather being operated upon may be exposed,and so that the operator mayconveniently place a die upon any or-- tionof the exposed surface. To this en the stock supporting bed is usuallyof a width such that the operator. may conveniently reach across it toplace a die uponany .part of its width and that he may convenientlyinspect the stock within the die which is position over the die in thenext'selecte location of the latter.

machine of-thetype of that just referred to is illustrated in LettersPatent of the United States, No. 921,503, dated 'May 11, 1909, and thepresent application is'a continuation of the application for said Let- 1ters Patent, so far as said applications disclose commonsubject-matter.When a machine of the type of that shown in the said patentisconstructed with a die blocker cut- BATES, a sub- 1 excess of weight,from drag ting bed of such a width and length as to permit convenientinspection of the stock lying upon it and convenient manipulation of thedie thereover, a portion of an ordinary skin, such as those from whichupper blanks are usually cut, will project over one edge of the dieblock and when the operator is cutting from the portion of the skinnearest to him it is necessary that a portion of the opposite side ofthe skin shall project over the edge of the die block remote from theoperator; In the machine of the patent above referredto the pressureapplying memberis connected to a support located behind the bed and inthe specific construction therein shown this support. is a verticallyreciproeating plunger to which the pressure applyin member-is secured.To facilitate handling of the material being operated upon and toprevent it from being injured or soiled by the machine, it is desirableto provide a recess between the bed and the support for the pressureapplying member to receive such surplus material as may extend beyondthe rear edge of the bed, and an important feature of the presentinvention is the provision not only of such recess but alsoof a materialreceivingtrough in said recess. Preferably this trough extendssubstantially the whole length of the bed.

Another important feature of the present invention is the provision of amaterial receiving trough between the bedand the support for thepressureapplying member which 'is so shaped that it will cause the material toroll back upon itself toward the bed and thus further prevent it fromcoming into contact with said support orother parts of the machine. Thetrough is also useful in supporting the weight of the surplus stock andpreventing it, through an mg the stock on the bed. .This function ofespecially advantageous when the operator is cutting blanks from theportion of the stock nearest to him or when he is dying out -blanks fromlarge skins.

' 'Another feature of the invention is the provision of an adjustableand detachable ably of sheet metal, so that-it may readily be. given anydesiredshape and'any deslred position inflrespect to the bed. Advantagesof making this trough of sheet metal are material receiving troughformed prefer-.

the trough is the cheapness of construction, the above sug gested readyadaptability to the various uses to which the machine may be put and itslightness.

The trough herein illustrated comprises preferably a piece of sheetmetal of a length substantially equal to the length of the bed bent intoU shape in cross-section and having its rear part somewhat higher thanthe front part and incurved and outcurved for purposes hereinafter to bepointed out. Clamp members carried by the trough are arranged to engageflanges provided upon the frame of the machine at the rear of the bed,this method of attachment of the trough to the machine frame permittingthe ready adjustment of the trough with respect to the bed and theplunger. The clamp members are preferably also so shaped-that the troughmay readilybe removed .when it is desired to clean it or to replace itby another of different size or shape. The trough being formed of sheetmetal, its shape, as above suggested,

may readily be changed to suit it to the different uses to which amachine of this type may be put.

Other novel features of the invention will be apparent from aconsideration of the illustrated construction in connection with thedescription thereof, and it is my intention to cover, inthe annexedclaims, all that is herein illustrated of my invention.

In the accompanying drawings,Figurel is a side elevation of a machine ofthe type of that disclosed in the patent, above referred to, havingembodied therein theinvention of this application; Fig. 2 is aperspective detail, partly in section, illustrating the construction andmanner of use of the stock supporting trough which forms the mainfeature of the present invention; and Fig. 3 is a sectional detailshowing the manner of attachment of the trough' to the frame.

The press to which the invention is herein shown as applied comprises,preferably, a cutting bed 2 secured to or formed as part of a frame landadapted to supporhlthe skin or other material.5 to be operated upon bymovable cutting knives or dies 7. Pressure applying means comprisingpreferably an arm 6 isarranged above the cuttingfbed, said meansbeing'secured by bolts 8 to a column or plunger 10 supported in bearingsI 12 and 14 on an upwardly extending portion 15 of the frame. The columnor plunger 10 is arranged to turn in said bearings so that the pressureapplying member may be positioned above the Work and dies or movedentirely clear of them by a movement of said means laterally in a planesubstantially parallel to the bed. The pressure applying means andcolumn are arranged to receive a vertical reciprocating motion so thatwhen the said means is lowered into contact with the die or dieslrestingu on the work, pres surewill beexerted an the work will be died out.When the said means is raised above the workit can be swung toa'position sufliciently removed from the ortion of the work beingoperated on .to a ord an unobstructed view of that part of the work, orit may be swung entirely clear of the bed. The vertical movement of thepressure applying means and its supporting column may be obtainedthrough any suitable mech-' anism, such, for example, as thatillustrated in the patent above referred to, said mechanism beingoperated from a driving pulley 20 which may be clutched at will to ashaft constituting a part of said mechanism. The clutch will bepreferably of the type that imparts one revolution to the-driving shaftand then automatically disconnects.-' Provision will preferably be madefor adjusting the pressure applying member vertically in order toaccommodate it to different depths of cutting dies. An operating handle36 cooperating with'a lever 40 pivoted upon the extension 15 of theframe at 42 is arrangedto operate the clutch and start the machine foreffecting a pressure applying operation at the will of the operatorthrough suitable connections 56, 58 and 62 with said clutch.

The foregoing mechanism, as well as that hereinafter described, issubstantially the, same as that illustrated and described in the patentabove referred to.

The cutting bed 2, which, in the preferred construction, comprises awooden block,is preferably of such dimensions that the operator mayconveniently place the die on any part thereof and' may inspect thestock .1

lying within the die, the die being-preferably formed entirely openwithin its outline. The block is therefore preferably of a width lessthan its length, the blocks employed in machines in commercial use beingusually about 18 inches wide and 36 inches long. When a skin is. placedupon such a block a portion of it, at the start, will usually projectbeyond one of the sides of the block and, for convenience inmanipulation of the skin and the dies it is preferable that the surplusproject beyond the edge of the block remote fron th'e operator,particularly when the operator is cutting from the portion of the skinnearest to him. To provide. for this, the machine is preferably soconstructed that there is a comparatively shallow recess between theblock and the bearing 14 for. the column or plunger lO in which thesurplus portion of the stock lying upon the cutting bed may be received,and preferably a throat or trough 33 is located in this recess tosustain the said surplus portion of the stock without soiling orwrinkling it. Preferably this throat 33 will be vsituated in front ofthe bearing 14 and the .verticaLcolumn 10 and will extend to eithereeopac metal bent into substantially a U shape in cross-section, one armof the U lying'just beneath the rear edge of the cutting bed 3 put andto the various the machine operates, and that by its method and theother arm of the U, which is some-i what longer than the.first-mentioned arm, lying adjacent to the bearing 14 and being recurvedsomewhat at its'upper end. The

recurving of the last-mentioned arm of the U or the back part of thetrough 33 is ofadvantage "not only in holding the stock out of contactwith the column orplunger 10 as it reciprocates, but in imparting to thestock asit comes into the trough a tendency to roll back "upon itself,thereby aiding-in preventing theformation of wrinkles, especially whenoperating upon stock such as patent leather.

The machine frame between the bearing 14 and the support for the cuttingbed 2 is provided with lateral flanges 35 to which the trough is clampedby suitable clamps 37. Theseclamps are attached to the trough byclamping bolts 39' about which they may be turned to permit theconvenient removal of the trough from the frame when it is desired toclean it, reshape it, or replace it by another.

It will be noted that the trough may readily be adjusted longitudinallyof the flanges to place it in different relations to the bearing 14: andthe cutting bed' 2;"that, being formed of sheet metal, it may readily bereshaped to permit its being suited to the various uses to which themachine may be materials upon which of attachment it may be readilyremoved for cleaning or to permit its replacement by another trough of.a different shape or Size or both.
